The Warragamba River was discovered by George William Evans in 1804 when he came upstream to the present site of the Warragamba Dam.  The town was original constructed as a workers’ settlement whilst the Dam was
being built to provide Sydney’s primary water source in the 1940s. The town was completely constructed from scratch including homes, shops, schools and other facilities. When the dam was finished the town was scheduled to be demolished but a community had been established and many workers bought their homes from the Water Board and stayed on in the township.
The unusual element about Warragamba is that the streets of the town do not have typical names but are numbered numerically, i.e. Nineteenth Street and First Street etc. (2)
